    Hydrogen H2 Gas Detector ApplicationsTips: Use Case - Portable Hydrogen (H2) Gas Detector for Fuel Cell Company

    A new energy company has been engaged in research and development, testing and production of various fuel cells for many years. The company has many hydrogen pipelines for the hydrogen (H2) is the main power source in the production process. To prevent the substandard process from the leakage of the hydrogen, the engineer made an inquiry about detecting the leakage of hydrogen to us.

    They needed a portable hydrogen detector to detect H2 leaks at the ports of each pipeline, record the detection value in real time and save a set of data every 2s recording interval. Furthermore, they also required transmitting the data to computer for the analysis.

    After the communication with the engineers based on their requirements, we recommended them a portable hydrogen (H2) gas detector ATO-SKY2000-H2, with measuring range of 0-1000ppm and resolution of 1ppm and also with data transmission and storage function.

    After using this H2 gas detector for a period of time, they were very satisfied with the detection results. The hydrogen gas detector not only is accurate in detection, fast in response time, but also real-time records the detecting value and save the data.

    Dear Noah, thanks for your ordering and comment. To ensure the accuracy of the measurement, our gas detectors adopt the high-performance sensor so the cost is relatively higher. Good gas detector deserves this price.

    Hydrogen gas detector
    Does your H2 gas detector continuously check the hydrogen leakage automatically or we need to check it manually?

    ATO Responded
    This detector can continuously check the hydrogen leakage automatically.
    Hydrogen gas detector 0-100%VOL
    Can we use your hydrogen gas detector to measure hydrogen in Air via selecting 0-100%VOL measuring range?
    From: Rob | Date: 20/04/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    No, the range 0-100%VOL is usually used to measure the purity of H2 in a single gas, so it is not suitable for measuring H2 in an air mixture.
    Using H2 leak detector for refrigeration piping system
    Hi. We are a chiller manufacture and we currently use a 95-5 nitrogen-hydrogen gas mixture to pressurize and leak test our refrigeration piping systems. We use the H2 leak detector to find out the leaks and was curious if you had any experience using this equipment for that purpose?

    Hi, Jed. You are welcome, but sorry to tell you, our portable hydrogen gas detector does not support H2 leaks test of refrigeration piping systems.
    A technical inquiry regarding your portable hydrogen gas detector (0-2000ppm)
    Hi. I have a technical inquiry regarding your portable hydrogen gas detector (0-2000ppm): what other gases can cause interference with the detection of hydrogen in this sensor? For example, we'd like to monitor hydrogen (0-2000ppm) in an exhaust gas stream that contains 73% N2, 12% O2, 10% H2O, 5% CO2, 2000ppm CH4, 500ppm CO, 500ppm NO and 750ppm NO2. Would the detector foul with these gases present?
    From: Scott | Date: 10/06/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hello, Scott. In your case, CO will interfere with the H2 detection. If there is 500 ppm of CO in the environment, then even if no H2 exists, the H2 gas detector reading will show 2000ppm.

    What is the frequency of calibration required for your H2 gas detector?
    Hi. What is the frequency of calibration required for your H2 gas detector?
    Can we do it locally? What is the cal gas you recommend?
    From: Sam | Date: 11/11/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, Sam. For your questions, please check answers below.
    1. Once a year.
    2. Recommended gas for calibration is 1:1 hydrogen.
    3. Yes, of course. You can perform calibration locally, by sending it to a local laboratory or calibration company for calibration. And we can send you the calibration operation video for your reference.
    Suppose I want to operate your portable hydrogen detector while it is being charged.
    Hi. Suppose I want to operate your portable hydrogen detector while it is being charged. Can I do that? The reason is that we do not want the battery to be drained so that the reading is wrong.
    From: Herbert | Date: 07/12/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, Herbert. We do not recommend operating the portable hydrogen detector while it is being charged, because it may cause unstable measurement. And our gas detector can generally be used for 20-30 hours after being fully charged.
    If you want to monitor the gas continuously for a long time (more than 24 hours), we recommend using the fixed gas detector.
    Hydrogen/methane detection
    Hello there.
    Since we only have a binary hydrogen/methane mixture and need to measure hydrogen, our thought was we could calibrate the unit using 100% methane as a zero or blank, and 100% hydrogen at the other end. The 2 gases have significantly different thermal conductivities, so as long your detector can provide accurate readings in such an environment, we can calculate the hydrogen vs. methane.
    From: John | Date: 16/12/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, John. First of all, our Portable Hydrogen (H2) Gas Detector (0-to 100% VOL) is only suitable for measuring a single gas environment, so it does Not work in your case.
    Then, we recommend using 0-100%VOL methane (CH4) detector (the lower limit of methane detection is 1%VOL), which can be used in different environments, and after the CH4 value is detected, then the remaining gas hydrogen can be calculated.
    I'm interested to order the hydrogen gas detector (0-500pm)...
    Hi. I'm interested to order the hydrogen gas detector (0-500pm) and therefore I got several questions.
    a) Could you explain how the detection is carried out during a measurement/pump cycle?
    b) What is the diameter of the air inlet of the portable detector system?
    From: Gauri | Date: 28/12/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, Gauri. You're welcome.
    a) For the hydrogen gas detector, it has a built-in suction pump, so the gas inside the chamber will pass through the sensor continuously, and the gas concentration accurately appears on the display of the gas detector. At the same time, in order to avoid residues in the air chamber, the gas detector is designed with an air outlet.
    b) The diameter of the air inlet is 5mm.

    Hello. We are interested in learning more about the Portable Hydrogen (H2) Gas Detector, 0 to 500/1000/2000 ppm unit. Given that this unit was designed for pure hydrogen, what are the anticipated effects if it’s exposed to hydrogen-methane blends or hydrogen-natural gas blends? Appreciate any insights you can provide.
